SUMMARY
The validity of a Bernoulli distribution probability function is confirmed by demonstrating that the sum of the probabilities for all possible outcomes equals one. Specifically, for a Bernoulli distribution with parameter p, the probabilities are defined as P(X=1) = p and P(X=0) = 1-p. Thus, the equation p + (1-p) = 1 validates that it is indeed a probability distribution function. This foundational concept is essential for understanding discrete probability distributions.
